Fisher 1270 manual Iron Disc Mode, All Metal Mode

ALL METAL MODE

metal. This may be tested quickly by pulling the trigger switch and sweep- ing over an area of about one square foot. If no signal is detected, release the trigger switch and raise the search coil off the ground, and lower it back down two or three times (also known as “bobbing”). If an audible sound is heard, turn the GROUND ADJUST knob slightly clockwise. Repeat this procedure until no sound is heard when raising and lowering the coil to the ground. Once you have the 1270 balanced to the type of ground you are searching, you may begin sweeping the coil at a comfortable pace. Approxi- mately four feet per second will give you optimal performance. Remember, the ALL METAL GROUND ADJUST mode is a MOTION mode. Slight movement of the coil is required to detect an object. While in this mode, if the IRON DISC toggle is OFF, pushing the MODE TRIGGER forward switches the 1270 into the NORMAL DISC mode. If the IRON DISC toggle is ON, pushing the MODE TRIGGER forward switches the 1270 into the IRON DISC mode. SEE PRIMARY & SECONDARY OPERATING MODES PG. 7)

IRON DISC MODE

Searching in IRON DISC may be preferred when small iron objects are to be rejected. In fact, this mode greatly improves the detectors ability to “see through” iron trash to the good non-ferrous targets often sought after. Make sure the ALL METAL GROUND ADJUST is OFF; that is, fully counter- clockwise until it “clicks” into the “0” position. Flip the IRON toggle switch up into the ON position. Adjust your sensitivity clockwise to the desired level (preferably until a slight threshold tone is heard, at about “8” or greater). Reduce the sensitivity slightly if you prefer silent search. In the IRON DISC mode, you have two features that enhance the performance of the 1270: the SILENCER and the IRON DISC adjust knob. The IRON DISC knob gives you the ability to “fine tune” the amount of iron you wish to reject. Turning the IRON DISC knob clockwise causes larger pieces of iron to be rejected. You may hear some normal “clicks and pops” when the coil passes over these targets. In high trash areas, turning the SILENCER toggle ON will reduce, and in most cases, eliminate the “clicks and pops”. Remember that the IRON DISC mode is a MOTION mode. Slight move- ment of the coil is required to detect an object. When IRON DISC is the primary operating mode, pushing the MODE TRIGGER forward switches the 1270 into the NORMAL DISC mode.
